[Haskell-cafe] Monads for Drummers! Yet another monad tutorial with pictures!

Yes! It's another monad tutorial. I've tried hard not to do it but finally it came out. I wrote a book on Haskell in Russian. It's a translation of the chapter that is dedicated to monads. I was convinced by friends to publish it. The monads are explained with pictures and Kleisli categories. Hope this can help to someone to grasp the monad concept. ------------------------------------- ps: pictures were made with diagrams Thank you for being kind with my awkward English!
